To all whom t may concern.'

Be it known that l, JOHN HARGER, a citizen of the United States, residing at Honolulu, Territory of Hawaii, have invented.

new and useful Improvements in Running- Stitch Sewing-Machines, of which the following is a specification.

This invention relates to a sewing machine and more particularly to that class of machines known as the running stitch type.

The object is to construct a machine especially adapted to sew strips of paper used for decorative purposes, the strip being crimped and sewed with a single thread, and a stationary needle being employed.

After the sewing and crimping operations are completed in this machine the strip is twisted for forming a round or spiral lai, as the article is termed in the Hawaiian Islands where it is used for the purpose indicated. It is the present practice to sew these strips of paper by hand, and by employing a machine of the type herein described a large proportion of the time required for the sewing and crimping operations may be saved.

A further object is to provide certain means of novel construction for retaining the needle in proper position, and certain adjusting means hereinafter described.

With the foregoing and other objects in view the invention consists in thenovel construction, combination-and arrangement of elements hereinafter described and claimed.

In the accompanying drawings:

Figure 1 is a view of the machine4 in side elevation,

Fig. 2 is a top plan view,

Fig. 3 is a side elevation of the rolls and mounting means therefor,`

Fig. 4 is an elevation of the device,

Fig. 5 is an elevation of the needle bracing device,

Fig. 6 is a vertical section of the needle holding device,

paper guiding Fig. 7 is a transverse section thereof, and

Fig. 8 is a detail of construction described below.

Fig. 9 is a detail rin section of the structure shown in the lower part of Fig. 5 for guiding the needle brace.

The base on which theoperative parts of the machine are mounted is designated 10 and at or near one end thereof is a device 12 constituting a paper guide and comprisinga (frame, the side members of which are designated 13 and 14, these members being properly secured by screws or the like shown at l5. lExtending between members 13 and 14 are a plurality of guiding devices 16 and 17 spaced apart and serving to mount the paper guides proper, the guides last named being designated 18 and 19 and each carrying a downwardly depending threaded member 20 engaged by a screw 21 provided with right and left hand threads 22 and 23. This screw has its bearings in the uprights 13 and 14 and is secured at one end by` a nut 24, the opposite end carrying a crank 25 provided with a socket member 26 engaging the end of the screw and having a shoulder 27 bearing against one side of the upright 13. This paper guide is designed to accommodate paper of various widths, say from 11; to 3, the strips of paper to be sewed usually being from 10 to 15 long.

The crimping rolls are mounted in the main frame 30 comprising a central horizontal portion 3l, uprights32 and33 and laterally extending foot members 34 and 35 Secured to the base 10V by means of bolts or the like designated 36. The crimping rolls are designated 41, 42, 43 and 44 and are mounted respectively on shafts 51, 52, 53 and 54, all of the rolls except that designated 44 being rigidly mounted with reference to the shafts and roll 44 being loosely mounted on its shaft 54. The shaft last mentioned is adjustable vertically within slots 45 provided in the frame, these slots being extended laterally as shown at 46 for the purpose of retaining the shaft temporarily when the roll is lifted during the operation described below.

Shaft 51 and its roll 41 are adjustable vertically to a limited extent, said shaft being mounted for movement in arectangular slot in the lframe members. The adjustable bearings for this shaft are designated 47, one of these bearings being provided on each side and being under the control of a threaded member 48 extending vertically through the frame and retained in position by a nut 48', a spring 49 encircling the member 48 at that portion below the frame.

The rolls 41, 42, 43 and 44 are each grooved as indicated at 50 thesergrooves p roviding .for the stationary needle which projects between the upper rolls and the lower rolls.

n crank 6l provides means for imparting modation of the thread passing to the needle,

and an adjusting screw 74 has its end portion extending into the channel in alinement/ with the needle. Extending transversely of.

the channel 73 is an adjusting screw 7 4 with which a screw 75 coperates for retaining the needle. Screw 75 is provided with a head 76 having a knurled edge portion for the purpose of permitting of easy adjustment.

Between the needle holding device and the crimping rolls I mount a needle brace the base portion of which is designated 80, the upright or uprights extending therefrom being shown at 81 and carrying a stationary transverse member 82 one end of which is provided with an upwardly extending portion having a flat surface 83 which is grooved at 84, this portion coperating with the corresponding portion or jaw 85 forming a portion of a pivoted lever 86, the opposite end of which is under the influence of a coiled sprin 87 normally holding the jaws of the devlce closed about the needle. This device serves to retain the needle in proper position with its point in polslition with reference to the grooves of the ro s.

The thread is designated 90 and passes to the eye of the needle at the point 91.

In operation, the paper guide is adjusted to the width of the paper being sewed and the paper strip is fed into the machine between crimping rolls 41 and 42. The roll 44 is raised temporarily to permit enough stitches to accumulate on the needle so that the paper may be stretched out beyond this roll. The latter is then restored to its normal or lower position and during the continued operation of the machine the stitched paper accumulates on that portion of the needle between the rolls 43 and 44 and the needle bracing device. The stitched portion is pulled by hand from the wheels until the needle is filled to its capacity at the point indicated. At this time the needle bracing device is opened by pressing upon the free end of lever 86 and is moved out of the path of the paper strip, the stitched paper being thrust toward the outer end of the needle when the brace is restored to its normal position, and the remaining portion of the strip being operated upon is sewed in the manner described. Finally the needle is removed from the brace and needle holder and the stitched paper is pulled on to the thread. The needle 4brace proper is movable with reference to the base 80 in view of the slot 88 and the guiding device 89 coperating therewith.

A U'-shaped frame designated 5 is located adjacent to the paper guiding device and the strip passes from this device 5 to the paper guide. The paper usually passes to the machine from a roll of paper merely dropped on the floor, and in order to prevent the strip from assing between the rolls in a twisted posltion, it is caused to travel over this frame 5 having a depressed central portion 6 which performs the function indicated.

It is obvious that any suitable source lof 'power may be used, such as a hand crank, a foot treadle, or a small motor.
